1. Introduction 1.1 Purpose of this document This document describes the universal measurement device SIRAX BT5200. It is intended to be used by: Installation personnel and commissioning engineers • Service and maintenance personnel • Planners • Scope This handbook is valid for all hardware versions of the BT5200. Some of the functions described in this document are available only, if the neces- sary optional components are included in the device.
3. Device overview The SIRAX BT5200 is a top-hat rail mounted Transducer and used to measure and convert AC Current input into an proportional DC current or voltage output signal. Input Current and Output Voltage/Current is displayed on LCD and indicated by LED’s. 4.
5. Electrical connections Ensure under all circumstances that the leads are free of potential when connecting them! 5.1 General safety notes Please observe that the data on the type plate must be adhered to! The national provisions have to be observed in the installation and material selection of electric lines! Symbol Meaning Device may only be disposed of in a professional manner!
6.1 Operating the device O/P1 O/P2 O/P1 O/P2 O/P1 O/P2 SIRAX BT5200 can be configured and programmed at site for the following: CT Primary, CT Secondary (5A or 1A), Input parameters (i.e start, end and INPUT x012 INPUT elbow value of Input) and Output parameters (i.e as Voltage or as Current and start, end and elbow value of outputs).
7. Programming Programming of transducer can be done in three ways: 1) Programming via Front LCD & two keys. 2) Programming via Programming port available at front of Transducers using optional PRKAB5000 adapter 3) Programming via optional RS485 (Modbus) communication port. 7.1 Programming via Front LCD &...
